What must we see to descend below mins?

• A. Flight visibility as per the approach
• B. TDZ in sight and you can land using normal maneuvers in the TDZ
• C. ALS in sight we can go to 100 feet above the TDZ
• D. All of the above

Answer: (D)

To descend below published minimums, you must have the necessary visual references and the required visibility. The flight visibility listed for the approach sets the minimum weather you must be able to see. Beyond that, you need a usable landing reference. If the touchdown zone is in sight and you can perform a normal landing from that point, you have the visual cues needed to continue and land. If the approach lighting system is in sight, you may descend to a point 100 feet above the TDZ and then proceed visually to land. Both the appropriate visibility and at least one of these landing references (TDZ or ALS cues) are needed, which is why all of the conditions are included.
